Council Island (formerly Mercer Island) hosts Seattle’s embassies with the nations of North America, part of a complicated political debacle involving the drafting of the Second Treaty of Denver and the section of the Seattle Metroplex Constitution that allows Seattle to send its own ambassadors and open its own embassies. At one time it was home to the rich and corporate of Seattle, but the eruptions of 2017 drove them off the island. Now most of the island is forested and undeveloped in accordance with an agreement with the Salish-Shidhe Council (which for several decades had complete jurisdiction over the island).
Housed along I-90 are the various embassies, with Seattle’s own embassies at both ends of the bridges as you enter or leave the island. The Salish-Shidhe and other NAN embassies are predominate, but you’ll also find embassies for the CAS, Tir Tairngire, Aztlan, Russia, Japan, Hong Kong, and the Canton Confederation, among others. The Corporate Court also has an office here. Construction on the isle is severely limited, with no structure allowed to be more than three stories high.
The Growp’skitch! sasquatch tribe inhabits the wild parts of the island, along with numerous critters and wildlife carefully watched over by park rangers. The sasquatch number over one hundred and fifty members, plus the occasional visiting sasquatch from out of town.
Espionage is the name of the game on Council Island. Any intel you can gather is worth something to somebody. Jurisdiction is a very carefully defined mess, so keep in mind that every nation has its own penalties for illegal activities. Unsurprisingly, the syndicates also keep a low-level presence on the island—diplomatic pouches are perfect for smuggling all manner of contraband, and the secure communication channels keep them in touch with operatives abroad.
